change freon 1

[19730206]

Good afternoon dear experts,
I need to replace R22 on R404A in a refrigerator (0 ? … +6 ?). I change compressor Embraco NE6181E on NE6181GK, I put the new (clean) evaporator and the condenser.
How to determine the sizes of a capillary tube and amount R404A?
what freon’s values of pressure and temperatures to be guided by?

Thanks for any advice
